The barbed-style Insert Nut For Wood Type B provides a strong, permanent thread for wood and wood based materials, providing substantial holding power even when torqued laterally.
The coarse external tooth (barbed) pattern ensures maximum holding power and simplified installation by knocking the Insert into the base material.
Insert Nut Type B features a round surface flange that increases its holding power and produces a finished appearance. The coarse external teeth and flange offer good retention on through-hole applications, while the internal threads ensure that connector bolts can be secured for furniture assembly.
